## Product description

1. To what kind of motor activity, according to the classification relates your sport?
a) locomotion (cyclic, acyclic)
b) conveying movement
c) maintaining and changing body position
e) motion on the spot

2. Formulate goals and objectives of the chosen type of motor activity

3. Analyze the kinematic characteristics in your sport:
a) draw a straight chronogram (timing diagram of movements) for athletes of varying skill (low and high) with the designation of phases, periods and boundary points.
b) Draw an example (schematic view of key moments in the boundary)
c) calculate the temporal characteristics (duration of phase, period, rhythm, tempo movements) for sportsmen of different qualification (specify tendency to change these parameters with increasing skill).

4. Analyze the dynamic characteristics:
c) Write the fundamental law of dynamics for sustained and
rotational motion:
d) analyze the mechanism of repulsion from the support of dynamic characteristics by calculating the angle of repulsion emission angle and distance of the long jump

5. Analysis of energy characteristics:

6. Methods of determining the GCM body:
Baseline: Ki
- Transfer techniques known to you:
a) Determine coordinate Uotsm using multiple regression equation obtained by applying the method for determining the radioisotope mass geometry of the body 100 subjects (VM Zatsiorsky 1979)
UOTSM = 11,6 + 0,675 X1 - 0,173 X2 - X3 0.299 (cm)
Where X1 - the length of the body, see X1 = 179,5
X2 - lower leg girth, X2 = 38.2 cm
X3 - Din housing X3 = 78.1 cm
b) calculate the coordinate Uotsm using multiple regression equations derived by comparing anthropometric indices 255 athletes of different qualification (cyclists, swimmers, tennis players):
Uotsm = -4.667 + 0.289 + 0.383 X4 X5 X6 + 0.301,
where X4 - foot length, 100 cm X 4 =
X5 - the length of the body = 166 cm X5
X6 - the width of the pelvis, X6 = 28.3 cm
The values \u200b\u200bobtained GCMs compare with table and conclude what sport could deal with this athlete, based on its anthropometric data
